Application filed September 20, 1924. Serial No. 738,811.

To all whom t may concern.'

Be it known that I, RACHEL E. HOFFMAN, a citizen of the United States, residing at Baltimore, in the city of Baltimore and State of Maryland, have invented certain new and useful mproveinents in Skylights; and I do hereby declare the following to be a full, clear, and exact description of the invention, suoli as will enable others skilled in the art to which it appertains to make and use the same.

The present invention provides for ventilating and admitting' daylight into buildings while excluding rain, snow and cold in wintertime. f

@ther objects and advantages will be apparent and suggest themselves as the nat-ure of the invention is understood.

While the drawings illustrate an embodiment of the invention it is to be understood that in adapting the same to meet different conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to without departing from the nature of the invention.

Referring to the accompanying drawings forming a part of the specification,

Figure 1 is a perspective view of a skylight embodying the invention,

Figure 2 is a vertical central sectional view thereof, and

Figure 3 a horizontal sectional view of the completed device on the line 3-3 of Figure 2.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

The numeral 10 denotes a roof plate in which is formed a central opening 11 to which is tted a closure 12 consisting of a hinged window sash which is closed in cold weather and open in warm weather. A tubular member 13 rises from the `roof plate 10 andV is attached at its lower end thereto and registers with the opening 11. A tubular member 14; of larger diameter than the tubular member 13 is disposed to receive the upper end of the latter from which it is yspaced as indicated at 15. A cap 16 closes the upper end of the tubular member 14C and is glazed to admit light and exclude rain, snow and the like. The cap 16 is likewise spaced from the upper end of the member 13 to admit of a free circulation of air between the two members 13 and 14 for proper ventilation. Braces 17 attached at their lower ends to the roof plate 10 and at their upper ends to the memberlt support theulatter and may be of any construction and arrangement.

`What is claimed is 1.. A sky-light comprising a roof plate having a centrally disposed opening, a tubular member attached to the roof plate and disposed in line with the opening thereof, and a tubular member light penetrable at the upper portion thereof receiving the upper end of the first mentioned tubular member and spaced therefrom to provide for a circulation of air while excluding rain, snow and the like.

2.. A sky-light comprising a roof plate having a centrally disposed opening, a tubular member attached to the roof plate and disposed in line with the opening thereof, a tubular member surrounding the upper portion of the rst mentioned tubular member and spaced therefrom, a light-penetrable glazed cap protecting and depending below the upper end of the second mentioned tubular member and connecting braces between the roof plate and the said second mentioned tubular member.

In testimony whereof I-afHX in presence of two witnesses.
